Picking the right differential ratio for your tire size and intended vehicle use is very important. Nitro engineered their Ring & Pinion gear sets to perform great as both a daily driver and weekend wheeler. And when you undergo difficult and unexpected yard work, such as hauling 10,320-pounds behind your Triple Transfer Case-equipped 3rd gen Tacoma on 40" tires, I'm happy to know Nitro 5.29:1 Tacoma Ring & Pinion Gears has my back!

We did a metallurgical comparison, conducted by a testing lab that does FAA forensic work, Pratt Whitney & GE engine parts testing, on Nitro Gear and Toyota ring and pinions. Results are: Both gear sets were identical in metal chemistry, machine finish & Rockwell.
